Sn Pb Tin Lead Solder Bar(Tin Lead Solder Stick)

You May Also Like:

Lichuang Sn-Pb tin lead solder bar is made of pure tin ingot and
highly purified 1# lead ingot. Featuring low melting point and good fluidity,
it is mainly used for the soldering of precision instrument, electrical and
electronic component, circuit board element, etc. 63Sn/37P solder bar is recognized as the best
tin lead solder, which is widely employed for its excellent soldering
performance.

Advantages of Sn-Pb Tin Lead Solder Bar

1. This
type of solder stick contains very little impurity.

2. Our
lead solder is processed through advanced melting and manufacturing technique.

3. Good
wettability and fluidity make it able to prevent the phenomena of bridging and
icicle effectively.

4. Solder
joint is with good mechanical property.

5. Sn-Pb
tin lead solder bar has function of anti-oxidation, so there is little tin slag
generated during soldering.

6. The
adding of additives changes the crystal structure of solder joints, reduces
internal stress and inhibits the growth of crystal.
